COUPLING DEVICE FOR CASH REGISTERS, CALCULATING MACHINES, OR THE LIKE.

Application filed December 29, 1921.

To all whom it may concern:

Be it known that I, Emvsr BREITLING, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Coupling Devices for Cash Registers, Calculating Machines, or the like, of which the following is a specification.

This invention relates to an apparatus for cash registers or calculating machines for selectively coupling one of a number of registering mechanisms, f. i. totalizing counters to operating members controlled by the setting mechanism of the machine. The object of the invention is to provide an apparatus of this kind which, f. i. in the case of cash registers which have the totalizing counters arranged in a drum, enables any totalizing counter to be selected and brought into engagement with the operating ment here without any rotation of the drum.

This object is realized by the fact that each registering mechanism carrier can have imparted to it the movement, required to connect and mechanism to and from the operating members, by a gearing member cooperating with a setting pin of the respective registering mechanism carrier, said gearing member, when the machine is operated, making a movement setting it to the setting pin of one of the registering mechanisms, and a second movement directed transversely to said setting movement.

The invention will be described with ref erence to an embodiment of the subjectmatter of the invention shown by way of example in theaccompanying drawing, in which,

Fig. 1 is a front elevation of a cash register with the drum in longitudinal section, certain parts being omitted for the sake of clearness.

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a cross section of the drum on the line 3-3 of Fig. 1.

Fig. 4 is a section on the line 41 of Fig. 1.

Fig. 5 is a view corresponding to Fig. 4 with some of the parts in a difierent position, and

Fig. 6 is a. section on the line 6- 6 of Fig. 1; all these sections being seen from the right.

disconnect the registering Serial No. 525,768. I

Fig. 7 shows the apparatus for throwing the totalizing counters into and out of the zero position and Fig. 8 shows the same apparatus with the totalizing counter thrown into operation.

Furthermore and on a. slightly larger scale Fig. 9 is rear View of a portion of the drum.

In the keybanks A are mounted five rows of amount keys B (see Figures 1 and 2) and one row of special keys C (see Figures 1 and The amount keys B 00- operate with feelers b of setting bolts 6 pivoted to driving sectors B and the special keys C provided for the selection of the totalizing counters'cooperate with a feeler 0 of a setting bolt 0 pivoted to a driving sector C The driving sectors B which are mounted to rotate loosely on a shaft B, are adjusted by means of driver discs I), which are rigidly connected to this shaft and to which a rocking movement is imparted by a crank gear when the cash register is operated.

The crank gear has a crank 25 (Figures 1 and 6) which is mounted on the shaft B and is connected by a rod (Z to a crank d mountedon a short shaft D. The shaft D which is mounted in the casing A is positively connected by gear wheels (Z d, to the actuating shaft D and makes one revolution each time the cash register is operated. \Vhen the driver disc 12 moves upwards its nose b (see Fig. 52) catches against the setting bolt 6 and carries the sector B with it, until by the feeler b striking against the tail of the depressed key B the setting bolt 6 is brought out of engagement with the nose N of the disc 12 and into engagement with a series of teeth (1, of the keybank thereby locking the sector B When the driver disc 6 moves downwards a pin 5 mounted thereon strikes against the sector B and moves it back into the zero position.

The gear wheel (Z gears into a gear wheel 6 of the same size (see Figures 1 and 6) which is mounted on a shaft E which carries a dlSC-E having a cam groove 6 (see Figures 4 and 5). Since, as above stated, the gear wheel (Z makes one revolution each time the cash register is operated, the disc E will also make one revolution each time the cash register is operated. A roller 0 mounted on a connecting rod C engages in the cam, groove. 6 The connecting rod (1 is guided by one, fork-shaped end on the: shaft E and at the other end it is pivoted to a rock lever C mounted on a shaft 0 The free'end of the lever C is'pivotally connected to a rod G which is pivotally connected by a bolt 0 to a driver disc 0 mounted to rotate on the shaiit B and provided for the driving sector G which is likewise mounted to rotate on the said shaft B.

By means of the above described gearing an oscillating movement is imparted to the driver disc 0 each time the cash register is operated, and. the cam groove 6 is: so formed; that the complete oscillatory move ment (upwards and." downwards) of' the special key driver disc 0 takes place during the downward: movement of theamount key driver discs 6 said first-named complete movement; of the driver disc: 0 consequently, being completed prior: to the counts ingfmovement of" the amount key driving sector,which movementtakes place on the: upward oscillation;

Then the driverdiscc swings upwards,- its nose 0 catchesv against the setting bolt 0 anjdi carries the sector G witlr it, until the;

feeler 0 strikes against the: tail of; a depressed special l teyi When the driver disc: 0 moves. downwards a pin 0 mounted on it strikes agai'nstifthei: sector C and: brings it back into the zero; position.

Into the: teeth: 6 (see Fig. 2-) of each sector B gears a wheelr b rotating on a shaft 6 (see Fig. 1) and adapted to be coupled by a rocking gear wheeli-b toa gear wheel 6 of thesame size rotatingon the: shaft 6 (*see Figures 1' and 2*). Each gear wheel} 6 gears into a wheel 7. The gear wheels f are mounted on the ends of hollow shafts F located within each other and enclosing a shaft G carried in the casing A and projecting into the drum G the latter being rigid'lyconnected tothe shaft Inside the drum G and on the end of each hollow shaft F is mounted'a toothed counting'disc f. The totalizing counters if which are mounted in frames H can be brought into engagement with the counting discs 1?. The frames for the totalizing counters, aremounted to rock, by means of bolts it in the end' walls 9 of the drunr G On each frame is mounted a roller 7291 By the cooperationof the rollers 72, withthe arrangement hereinafter described the oscillating motion required to throw the totalizing counters into or out of operation is impartedto the frames Into-the'teeth 0 of the sector gears an intermediate wheel 2' (see F ig: 1) which rotates on the shaft Z9 (see Fig. 4-)" and gears into a: gear wheel 7?. This gear wheel is mounted on one end of a hol low shaft 2' surrounding the outermost hollow shaft F', the oth'erend of said shaft 2' carrying a pressed keys.

slot-ted disc J. In a corresponding manner. a cam groove disc K is positively connected to the driver disc 0 by an intermediate wheel Z0 rotating on the shaft 6 and engaging a series of teeth c 'on the disc 0 also by a gear wheel'lc cooperating with the wheel [a and a hollow shaft surrounding the hollow shaft 2' T A sliding block J (see particularly Figures 7 and 8) is movable radially on'the slotted disc J. The-sliding block: J is orovided witha segment-shaped groovez' which runs through. it. andcompletes. an. annular groove 71*" leading from) both. sides upto the sliding block: and concentric with the hollow shaft i into'a' closed ring which runs acrossithe; sliding block J when this latter is in its extreme outer position (see Figh'fl). In. this annular groove: engage the: setting pins: (irollers h of the totalizing counter carriers H, so that: by rotating the disc J the: sliding" block J 03111138? set either to the roller 75 of.' totalizing counter carrier or to-the1 idle position (see Fig. 7).-

The: movement of t-hezsli'cling block J is efiectedbymeans of'the portion 76 of a camgroove la? Ka -provided in the disc K and in with the portion la of" the groove, the slid-- mg block J is in -its inner position: During this time, the totalizing counter, the setting roller h ofwhich engagesin the groove of the sliding block, is coupled to the countingdiscs 75 If, onthe rotation of the disc K, the r-ol ler z" ismoved int'o the portion k of thegroove 70 is the" sliding block J*' is movediradiall y' and the totalizing counter carrier rocked about the axis of the bolts 721 i The action of the above described arrangement is as fol lewsz 0 By depressing amount keys B, thesetting of the corresponding counting discs 7 is prepared and by depressing one of the spee cial keys C the setting of the corresponding 7 \Vhen the cash reg- V totalizing counter [L11 iste'r is operated firstly the driving sectors B for the amountkeys are brought back by the driver discs Z9 out of the position stil l 'assumecl by them owing to the previous operation of the cash register, into the zero position, the coupling gear wheels 6 being out of engagement, so that thecountingdiscs f are not connected tothesectors B. These latter are then carried upwards by the driver discs 6 until they strike against the de r The counting movement of the sectors B which is limited by this striking is transferred to the counting discs. 7' whichare positively connected to-the sectors B after the coupling wheels 6 have been thrown into operation, and to the totalizing counter h? in engagement with the. counting discs f WVhen no special key C for one of the totalizing counters is depressed the sector C is moved by the driver disc up to the uppermost position, in the cash register shown (see Fig. 4) up to the tenth place. I11 all other respects the action of the driver disc 0 and of the sectorc which forms the setting member of the cash register serving to select the totalizing counter, is the same as that of the driver disc 6 and the sectors B of the mechanism for setting the amount. The adjustment is, however, effected by the operation of the cam E so much more rapidly that the complete to and fro-movement of the driver discs (downwards and upwards) has already been ended when the discs 6 and the sectors B have arrived in the zero position (below). w

When the driver disc '0 moves downwards the cam groove of the disc J positively connected to the driver disc 0 moves the sliding block J 4 out of the innerposition still assumed by it owing to the previous operation of the cash register, so that any roller h of a carrier H, just in engagementwith the groove 2' of the sliding block J is moved back into the path of the annular groove cl of the slotted disc J and the particular totalizing counter brought out of engagement with the counting discs f If the sliding block J had been set to the idle position, this reversal of the sliding block takes place during a rotation of the disc K, which corresponds to the rearward movement of the sector C and of the driver disc 0 from the tenth to the ninth position, and if the sliding block J had been set to one of the rollers it this reversal of the sliding block takes place in each case, correspondingly, before the point of the groove portion 10 coincides with the radial centre line of the sliding block J Now when all the rollers h of the carriers H have been brought into the path of the annular groove 71 of the disc J the rear ward rotation of the disc J can take place, which is efiected by the contact of the pin 0 with the sector C positively connected to the disc J After the sector C and the driver disc 0 have been returned to the lowest position (see Fig. 5) the disc 0 is again moved upwards by the reversal of the thrust crank gear, the setting bolt 0 of the sector C being carried along by the nose 0 of the disc 0 until it strikes against the key, and thereby being released from the driver disc C and locked. By this adjustment of the sector C and of the slotted disc J positively connected to it, the sliding block J 4 is set to the totalizing counter carrier corresponding to the depressed special key,'after which the cam disc K which has been moved on to the tenth place moves the sliding block J inwards by means of the groove portion 7: and the roller 2' and throws the selected totalizing counter 7& into gear with the teeth of the counting discs 7. Now by coupling the gear wheels o b the positive connection of the amount key sectors with the corresponding counting discs 7 is effected which sectors have been moved downwards in the meantime, these sectors then being set by the upward move ment of the driver disc If. VVhen this takes place, the counting movements imparted to the sectors B are transferred, by means of the countingdiscs f to the particular totalizing counter 72, which has been thrown into 0' eration, After the counting movement ias terminated the gear wheels I), 6 are disconnected and then the tens transfers (prepared by running past the ninth figure of the totalizing counter carriers) to the counting wheels of the next higher order are effected in a suitable manner (not shown in the drawing).

In addition to being used for cash registers of the kind described, the new apparatus can also be used for such constructions in which the totalizing counters are arranged in a circle round setting discs and are arranged to be directly brought into engagement therewith. The apparatus can also be used for throwing into action totalizing counters which are arranged along racks acting as setting members or operated by setting members of the machine. In such a case the groove of the slide block carrier would have to be in the form of a straight line and the cam groove in which the setting pin of the sliding block engages, would have to run, to a partial extent, parallel therewith.
